The midpoint of GH is M (2,2). One endpoint is H (1,9). Find the coordinates of endpoint G. A
(0, 16)

B
(1.5, 5.5)

C
(-0.5, 3.5)

D
(3, -5)

( 3,-5)

Step-by-step explanation:

To find the midpoint add the two end point coordinates and divide by two

Let G be ( x,y)

The midpoint of GH is (2,2)

( x+1) /2 = 2

Multiply by 2

x+1 = 4

Subtract 1

x+1-1 = 4-1

x=3

( y+9) /2 = 2

Multiply by 2

y+9 = 4

Subtract 9

y+9-9 = 4-9

y = -5

The coordinates of G is ( 3,-5)
